Why do fans spin backwards slightly after they (should) stop?

Why can you in physics exercises neglect the effect of air drag in case of basketball but not in the case of ping pong ball?

What happens when the drag force exceeds the weight of an object falling into earth?

Why are golf balls the only (famous) object with dimples?

Why do spaceships heat up when entering earth but not when exiting?

Would a projectile (arrow, bullet) with holes drilled in its length be faster and have greater range?

Theory behind the relationship between the mass of a cylinder and the time taken for it to roll down an incline - air resistance?

Why doesn't car fuel/energy consumption scale like the cube of the velocity?

Why is the damping force proportional to $v$ and not $v^2$?

In what scenarios would adding more mass to an object being thrown allow for more distance with the same force?
